Hi,
Sorry for the inconvenience this has caused. As Google has changed the mechanism of Android, if your phone is running Android 4.4+, a long text message sent by AirDroid will be split into several parts on your side while the recipient receives one whole message. We did try to find a workaround to this problem, but due to technical limitations, we didnât find a perfect solution. However, weâll keep on searching for a fix. To get the latest update on this, you can follow us on Twitter/Facebook/Google+.
